Answer:
40
Step-by-step explanation:
Answer:
5x^7y^11.
Step-by-step explanation:
∛(125x^21 y^33)
The cube root = 'to the power 1/3' so we have:
125^1/3 * x^(21*1/3) * y^(33*1/3)
5x^7y^11.
Answer:
2 - 4
Step-by-step explanation:
no equal sign
Answer:
hole at x=-3
Step-by-step explanation:
The hole is the discontinuity that exists after the fraction reduces. (Still doesn't exist for original of course)
The discontinuities for this expression is when the bottom is 0. x^2-9=0 when x=3 or x=-3 since squaring either and then subtracting 9 would lead to 0.
So anyways we have (x+3)/(x^2-9)
= (x+3)/((x-3)(x+3))
Now this equals 1/(x-3) with a hole at x=-3 since the x+3 factor was "cancelled" from the denominator.
